What distinction does fixed frequency and inverter refrigerator have? Which one is better?
Refrigerator is one of the most common household appliances in daily life, it is mainly divided into two types: frequency conversion and fixed frequency. In recent years, with the continuous development and improvement of frequency conversion technology, commercial freezers have gradually applied inverter technology, which performs well in both refrigeration and energy saving.
Many consumers do not know how to choose when buying commercial freezers, and often struggle between frequency conversion and fixed frequency. In fact, the inverter refrigerator has its technical superiority, but the traditional fixed frequency refrigerator also has the price advantage, two kinds of refrigerators can meet different preservation needs. So how to choose the refrigerator, quality and price are the key.
The most important is, buy variable frequency refrigerator or fixed frequency refrigerator needs to choose according to oneself actual demand. Let's look at the differences:
The speed of the compressor can be adjusted. It uses frequency conversion compressor, and adds frequency conversion controller in the refrigerator control system, by changing the speed of the compressor can change the cooling capacity of the refrigerator. When the refrigerator load is large, the compressor can operate at high speed, and the cooling capacity of the compressor is large to achieve rapid cooling. When the refrigerator load is low, the compressor can operate at a low speed. At this time, the compressor cooling capacity is small, which can reduce the start times of the refrigerator, and greatly extend the service life of the refrigerator.
The inverter refrigerator can make the temperature control in the refrigerator more accurate and stable, making the food temperature impact smaller, and reduce the loss of food water. Because the cooling capacity can be adjusted, the cooling capacity of the refrigerator can be well matched with the load of the refrigerator, to avoid unnecessary energy consumption and reduce power consumption.
Fixed frequency refrigerator:
The speed of the compressor is fixed, generally in 295O-3 OOO turns. When the set temperature is reached, the compressor stops running. When the temperature rises to a certain level, the compressor starts. It is through the compressor stop or start to control the temperature, repeated temperature impact on the food, the temperature control accuracy is worse than the inverter one. Fixed-frequency refrigerator mainly relies on the stop and start of the compressor to realize the temperature control.
◆ The compressor of the inverter refrigerator can adjust the rotation speed according to the refrigeration needs of the refrigerator. It can achieve accurate control of the temperature, to ensure the stability of the refrigerator internal temperature, so the preservation effect is good.
◆ Fixed-frequency refrigerator because the power of the compressor is constant, so the output of the cooling capacity is also constant. It has relatively poor temperature control, the temperature inside the refrigerator is not balanced and the preservation effect is poor.
◆ The frequency conversion technology adopted in the operation process of the inverter refrigerator can accurately control the speed of the refrigerator compressor and save electricity relatively.
◆ The fixed frequency refrigerator depends on the stop and start of the compressor to control the internal temperature, so the power consumption is large when the compressor is started.
◆ The compressor of inverter refrigerator does not need to start frequently, so the noise generated is lower.
◆ Fixed frequency refrigerator in the process of operation of its compressor frequently start, producing more noise.
Frequency frequency refrigerator because the technology is more advanced, more intelligent, so the price is higher. But the work efficiency is high, so it can also save more electricity and energy saving.
The compressor of the fixed-frequency refrigerator needs to start and stop frequently and run constantly. But the compressor of inverter refrigerator does not need to start and stop frequently, so the wear is smaller, relatively speaking, the service life of frequency conversion refrigerator is longer.
Above is the difference between the frequency conversion refrigerator and the fixed frequency refrigerator, did you understand? Must combine yours actual needs, distinguish clearly to buy.
